Solution: Logger Rate Limiter

Explore how to build a logger rate limiter that filters duplicate messages within a given time window using hash maps. Understand both naive and optimized approaches, analyze their time and space complexity, and learn to efficiently determine message display eligibility based on timestamp comparisons.

Statement

For the given stream of message requests and their timestamps as input, you must implement a logger rate limiter system that decides whether the current message request is displayed. The decision depends on whether the same message has already been displayed in the last SS seconds. If yes, then the decision is FALSE, as this message is considered a duplicate. Otherwise, the decision is TRUE.

Note: Several message requests, though received at different timestamps, may carry identical messages.

Constraint:

  • 11 \leq request.length 102\leq 10^{2}
